Definitions

  • the present invention refers to a gripper for retaining bottles according to the preamble of the independent claim.
  • the present gripper is inserted in the field of industrial bottling plants and is intended to be advantageously employed on a machine with rotary turntable, such as in particular a rinsing machine, for retaining the bottles during their operative travel around the rotation shaft of the rotary turntable.
  • Rotary turntable machines are known in the industrial bottling plant field; such machines are employed in bottling lines in order to subject the bottles to a specific treatment (such as rinsing machines, filling machines, etc.), or to transport the bottles from a machine upstream to a machine downstream of the line.
  • a specific treatment such as rinsing machines, filling machines, etc.
  • rinsing machines of known type are conventionally provided with a fixed support frame on which a rotary turntable is rotatably mounted, which peripherally supports a plurality of grippers adapted to grasp the bottles to be rinsed and arrange them overturned above the corresponding nozzles, through which a sanitizing fluid is injected inside the bottles themselves.
  • each gripper is conventionally provided with a pair of arms that can move between an open position, in which respective retention portions of the arms are spaced from each other in order to receive or release the bottle, and a closed position, in which the retention portions of the arms are moved close together in order to retain the bottle between them, at the bottle's neck.
  • Each gripper is also mounted on a corresponding tilting fork, which is rotatably constrained to the turntable, and is susceptible to rotate 180° around a horizontal rotation axis in order to overturn the bottle retained by the arms of the gripper and arrange the bottle itself overturned above the corresponding injection nozzle for the sanitizing fluid.
  • the arms of the grippers for retaining the bottles are each provided with a grip pad of plastic material intended to cooperate with the pad of the other arm in order to retain the bottle by abutting against the external surface of the neck of the bottle itself.
  • each pad is shaped with a semicircular recess at which the pad abuts against the neck of the bottle.
  • Such recess is shaped with a diameter substantially equal to the diameter of the bottle neck, in a manner such to be adapted to follow the form of the external surface of the bottle neck as much as possible in order to facilitate the correct retention thereof.
  • the main drawback of the rinsing machine described in the patent IT 1333259 consists of the fact that the aforesaid grippers do not allow retaining the various bottle types in a sufficiently firm manner, and hence they require the substitution of the pads with others with greater height for maintaining the bottles sufficiently firm. This requires interrupting the functioning of the rinsing machine in order to manually substitute the pads of the arms of all the grippers, with consequent lengthy production dead times.
  • the retention systems of known type are not capable of firmly retaining large-size bottles with a single gripper, with the risk that they will fall from the gripper during the tilting thereof.
  • rotary turntable machines are also known that are employed for transferring bottles between the different machines of the bottling line; in the jargon of the field these are termed "star conveyors".
  • the latter comprise a plurality of grippers, each provided with two pairs of superimposed arms, a lower and an upper arm, both susceptible to grasp the bottle at the enlarged body of the latter.
  • a gripper embodiment of the latter type is described in the German utility model DE 20305988 ; such document regards a gripper provided with a support body to which the arms of each pair of arms are pivoted by means of corresponding pins.
  • the arms of the gripper are rotated between the corresponding open and closed positions by a control rod, which is arranged between the retention portions of the arms of each pair and acts with a shaped profile thereof on discs mounted on the arms themselves.
  • Each arm is provided with a rear portion which is extended from the side opposite the retention portion with respect to the corresponding pin, and is much shorter than the retention portion itself.
  • Each pair of arms of the gripper is provided with two return springs, each of which mounted to connect the rear portions of the corresponding arms in order to return the latter into the closed position.
  • the main drawback of the grippers of known type described in the utility model DE 20305988 consists of the fact that they are not adapted to firmly retain the bottles, since the length of the rear portions of the arms (on which the return springs act) is much smaller than that of the retention portions and therefore the force exerted by the latter on the bottle is much less than that exerted by the springs on the lower portions of the arms.
  • the grippers described in the utility model DE 20305988 are only arranged for grasping the enlarged body of the bottles with a force sufficient for horizontally driving them around the axis of the rotary turntable, but not sufficient for allowing the gripper to retain the bottle during the tilting of the latter, as occurs in the rinsing machines.
  • the grippers of the star conveyors of the above-described type are not at all employable in the rinsing machines, since they have excessive size and bulk that would not allow the installation thereof on the tilting fork of the rinsing machines themselves.
  • grippers of known type are not adapted to firmly grasp bottles with non-cylindrical enlarged form (e.g. oval, square form, etc.) or provided with handle (such as flasks, etc.).
  • a further drawback of the gripper described in the utility model DE 20305988 is due to the fact that the control rod of the arms must be actuated both for opening and closing the arms themselves by suitable cams of the star conveyor, with consequent structural complications of the star conveyor itself.
  • control rod between the retention portions of the arms makes the gripper relatively bulky and structurally complex.
  • the problem underlying the present invention is to overcome the drawbacks of the prior art, by providing a gripper for retaining bottles that is structurally simple and entirely reliable in operation.
  • Further object of the present invention is to provide a gripper for retaining bottles capable of firmly retaining the bottles, in particular those with different format and large size.
  • Further object of the present invention is to provide a gripper for retaining bottles which allows being employed in a versatile manner upon varying the format of the bottles without having to carry out arduous adjustments or substitutions of parts of the gripper itself.
  • Further object of the present invention is to provide a gripper for retaining bottles that is compact and at the same time structurally simple and inexpensive to manufacture.
  • Further object of the present invention is to provide a gripper for retaining bottles that allows retaining the bottles centred in the respective seats on the turntable upon varying the formats thereof.
  • Further object of the present invention is to provide a gripper for retaining bottles which allows executing a change of format of the bottles without interrupting the production line.
  • an embodiment of the gripper for retaining bottles, object of the present invention is indicated in its entirety with the reference number 1.
  • the present gripper 1 is in particular intended to be employed in a machine 100 with rotary turntable.
  • the machine 100 is conventionally inserted inside a bottling plant upstream of a filling machine, in order to subj ect the bottles 2 to a rinsing treatment for ensuring a suitable sanitizing of the bottles 2 that will be filled in the filling machine downstream.
  • the bottles 2 are transferred from one machine to the other by means of conveyor lines, such as conveyor belts, star conveyors, screws, etc.
  • the present machine 100 is provided with an inlet station, at which it receives (by means of a first star conveyor) the bottles 2 to be rinsed that are brought by a first conveyor belt upstream, and an outlet station, at which it releases (by means of a second star conveyor) the rinsed bottles 2 to a second conveyor belt downstream, adapted to convey such rinsed bottles 2 to the filling machine downstream.
  • the bottles 2 are provided in a per se known manner with an enlarged body 2' terminating on the lower part with a support base, and from which a neck 2" is extended on the upper part, made narrow and provided at an upper end thereof with a mouth 2"' for the passage of an alimentary liquid contained in the bottle 2 itself.
  • the machine 100 comprises a support frame 101, set on the ground, on which a rotary turntable 102 is rotatable mounted, adapted to rotate around its vertical central rotation shaft 103.
  • the machine 100 further comprises a plurality of the aforesaid grippers 1, object of the present invention, arranged peripherally on the rotary turntable 102.
  • each of such grippers 1 is provided with a corresponding tilting fork 104, which is rotatably constrained to the rotary turntable 102 and is susceptible to rotate around a horizontal tilting axis X thereof, for tilting the bottle 2 retained by the gripper 1 itself.
  • each tilting fork 104 is hinged to a connection bracket 105 fixed to the rotary turntable 102.
  • the tilting fork 104 can be actuated to rotate 180° around its tilting axis X by a tubular cam arranged fixed around the rotation shaft 103 of the rotary turntable 102, in order to move the bottle 2 retained by the corresponding gripper 1 between an erect position, in which the bottle 2 is susceptible to being grasped or released by the gripper 1 (respectively at the inlet station and the outlet station of the machine 100), and an overturned position, in which the bottle 2 is retained by the gripper 1 with the mouth 2"' aligned with the supply opening of a corresponding nozzle 106 of the machine 100.
  • each nozzle 106 of the machine 100 is connected, by means of a corresponding connector tube 107, to a sanitizing fluid feed circuit, and it is susceptible to inject such sanitizing fluid into the bottle 2 retained by the gripper 1 in overturned position in order to wash the internal surface of the bottle 2 itself.
  • the gripper 1 comprises a support body 3 intended to be mounted on the rotary turntable 102 of the machine 100, and a first pair 4 of first arms 5, which are pivoted on the support body 3, by means of respective first pins 6 having corresponding first rotation axes Y' parallel to each other, and are provided with respective first retention portions 5' intended to grip the neck 2" of the bottle 2 to be grasped, and with respective first actuation portions 5" arranged on the side opposite the first retention portions 5' with respect to respective first pins 6.

  • the first pair 4 of first arms 5 and the second pair 7 of second arms 8 are susceptible to retain the neck 2" of the bottle 2, at two sections of the neck 2" that are spaced from each other. Consequently, the moment exerted by the weight of the bottle 2 on the neck 2" of the latter during tilting is exerted in a distributed manner on the retention portions 5', 8' of the two pairs 4, 7 of arms and hence in an improved manner with respect to the currently known grippers which provide a single pair of arms.

  • first and the second arms 5, 8 are subjected to the return action exerted respectively by the first and the second spring 34, 35 respectively through the first and the second slider 22, 23, and they are closed until they abut against the outer surface of the neck 2" of the bottle 2 to be retained with the retention portions 5', 8' thereof.
  • first and the second spring 34, 35 in engagement respectively on the first and on the second slider 22, 23 allows such springs 34, 35 to actuate the closure respectively of the first and second arms 5, 8 without the active intervention of any other actuation element, due to the simple disengagement of the cam followers 42, 43 of sliders 22, 23 from the fixed cam of the machine 100.
  • the first and the second closed position respectively of the first and the second arms 5, 8 are independent of each other, since the movement of the arms 5, 8 of each pair 4, 7 is actuated by separate movement means 24, 25 advantageously by means of the return actions respectively of the separate first and second spring 34, 35.
  • each pair 4, 7 of arms 5, 8 in closed position is determined by the stopping of the closing rotation of the arms 5, 8 abutted against the external surface of the neck 2" of the bottle 2, and therefore depends on the width of the neck 2"of the bottle 2 at the section of the neck 2" where the latter is retained by the arms 5, 8.
  • the angular opening of the first pair 4 of first arms 5 in the first closed position will therefore be different from the angular opening of the second pair 7 of second arms 8 in the second closed position, if the neck 2" of the bottle 2 has different widths at the sections where it is retained by the two pairs 4, 7 of arms of the gripper 1.
  • the invention thus conceived therefore attains the pre-established objects.
  • the configuration of two pairs 4, 7 of arms 5, 8 susceptible to act on the neck 2" of the bottle 2 in two spaced sections of the neck 2" itself, with independent closed positions, allows firmly retaining bottles of large size and of different type, especially without requiring adaptations or substitutions of components of the gripper 1.
  • such configuration of the gripper 1 allows retaining the bottle 2 centered with respect to the median plane ⁇ of the gripper 1 itself, and in particular allows retaining the bottle 2 in overturned position with the mouth 2"' aligned with the supply opening of the nozzle 106 of the machine 100.
  • the arrangement of the support body 3 of the gripper 1 as pivoting element for the arms 5, 8 and as sliding support for the sliders 22, 23, and in particular also as abutment for the springs 34 and 35, allows attaining a compact gripper that is simultaneously structurally simple and inexpensive to manufacture.
